What this server can do

2 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

get_call_status(call_id)
Poll the status of a call previously placed with place_call. Returns a CallOutcome with one of these statuses (in roughly likely order): queued/placing/ringing/connected — call still in progress, poll again in a few seconds completed — call finished cleanly, structured result available partial — call finished but some questions unanswered voicemail — recipient was voicemail; identified message left no_answer — recipient never picked up busy — recipient line was busy invalid_number — number is not in service rejected_ai — recipient declined to talk to A.I. (do not retry) needs_user_input — recipient needs info only the user can provide online_only — recipient said the task can only be done online timed_out — call exceeded max duration carrier_failure — telephony provider error (safe to retry later) api_error — internal failure (safe to retry) Always carries a free-form `exit_reason` string suitable for showing the user. Required: call_id.
place_call(user, safety, target, instructions, output_schema, idempotency_key)
Place an outbound phone call to a US business or person. The A.I. assistant on the call will identify itself as A.I., follow your instructions, and return a structured outcome via get_call_status. USE THIS TOOL WHEN: the user wants to make a phone call, contact a business by phone, ask about hours/pricing/availability, book a reservation, gather info that's not online, follow up on a service request, or do any task that requires talking to a human on the phone. LIMITATIONS: - US phone numbers only (E.164 starting with +1). International is not yet supported. - English language only. - Cannot call emergency services (911, 988, etc.) — these will be rejected. - The A.I. will NOT commit to bookings/payments without user confirmation unless safety.must_confirm_with_user is explicitly set to false. - Default 5-minute call duration cap. Returns immediately with a call_id. Poll get_call_status(call_id) for the result. Required: user, target, instructions, idempotency_key.

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
